Building Qt fails with missing dxgil_3.h
-
I'm trying to build qt-everywhere-src-5.14.2 on Windows 10 using MinGW.
I get: fatal error: dxgi1_3.h: No such file or directory
Seems the multimedia module is not successfully built.
I'm building for DirectShow: Checking for DirectShow... yes
What is this dxgi header and why is it missing - where can I get it?
Sounds like a DirectX thing but I can not even find this in Windows SDK.g++ -c -include .pch\debug\qt_gui_pch.h -fno-keep-inline-dllexport -msse2 -mstackrealign -mfpmath=sse -g -Og -std=c++1y -ffunction-sections -fdata-sections -fno-exceptions -Wall -Wextra -Wextra -Wvla -Wdate-time -DUNICODE -D_UNICODE -DWIN32 -DMINGW_HAS_SECURE_API=1 -DQT_STATIC_BUILD -DWINVER=0x0601 -D_WIN32_WINNT=0x0601 -DQT_NO_LINKED_LIST -DQT_NO_JAVA_STYLE_ITERATORS -DQT_NO_USING_NAMESPACE -DQT_NO_FOREACH -DMD4C_USE_UTF8 -DQT_NO_NARROWING_CONVERSIONS_IN_CONNECT -DQT_BUILD_GUI_LIB -DQT_BUILDING_QT -D_CRT_SECURE_NO_WARNINGS -D_USE_MATH_DEFINES -DQT_NO_CAST_TO_ASCII -DQT_ASCII_CAST_WARNINGS -DQT_MOC_COMPAT -DQT_USE_QSTRINGBUILDER -DQT_DEPRECATED_WARNINGS -DQT_DISABLE_DEPRECATED_B

Were you able to resolve this issue? I just tried to build Qt 5.15 (skipped the 5.14 releases) and bumped into the same error.
Any hint of where to look would be much appreciated.

I'm building on a docker of Fedora 30 with MinGW tools. The 1_3.h file can be obtained through the msys installer on Windows, but it makes a compile error, however, replacing the include directive in the _p_p.h file to include 1_2.h works for that file. Later on, there is a compile error missing some #defines which must be copied from the 1_3 file. It's a rats nest, but its possible.
